Answer:
kill cells and tissues outright
Explanation:
Sometimes bacteria multiply so rapidly they crowd out host tissues and disrupt normal function. Sometimes they kill cells and tissues outright. Sometimes they make toxins that can paralyze, destroy cells' metabolic machinery, or precipitate a massive immune reaction that is itself toxic

Describe the structure and parts of DNA molecule
Answer:
The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), and thymine (T).

Why are common cold viruses difficult to cure?(1 point)
A copy of the DNA is made from the viral RNA.
The virus leads to other viral infections such as the flu and HIV.
The viral genome mutates very quickly.
Vaccines prevent the development of a cure.
Answer:
You are very correct the answer is c
Correct option is ''The viral genome mutates very quickly.''
Viruses can't reproduce on their own as bacteria do, instead, they attach themselves to healthy cells and reprogram those cells to make new viruses. It is because of all of these differences that antibiotics don't work on viruses. Antibiotics and medications treat bacterial infections. These antibiotics cannot treat or cure a common cold as colds aren't caused by bacteria.
Common cold viruses are difficult to cure as the viral genome mutates very quickly.

The bright color pigment of some frogs is processed as a warning to vampires. This chemical defense is understood as poisonous.
What is Chemical defense?
These bright colors serve as a warning to predators: "Don't consume me; because it is poisonous." In this consideration, frogs aren't overhead bluffing.
Some nonpoisonous species of frogs have assumed the colors of poison dart frogs to trick vampires into offering them an expansive berth they don't earn.
This technique is prompted by melanin, a dark pigment. These frogs usually combine in with their surroundings and their skin functions as camouflage.
Different anurans are brightly embroidered. When If the bright colors alternate with opaque splotches the coloring may serve as a warning to predators that the frog or toad is poisonous.

Albinism is a recessive trait where an individual does not produce the pigment melanin. A man and woman both produce melanin, but both have one parent with albinism. What is the probability that their first child will have albinism
Answer:
The child has a 1/4 chance of having albinism
Explanation:
I hope this helps!
For most types of OCA, both parents must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation but still, carry the gene. When both parents carry the gene, and neither parent has albinism, there is a 25% chance at each pregnancy that the baby will be born with albinism.
What is the probability that their first child will have albinism?
This means a child has to get 2 copies of the gene that causes albinism (1 from each parent) to have the condition. If both parents carry the gene, there's a 1 in 4 chance that their child will have albinism and a 1 in 2 chance that their child will be a carrier.
Do both parents have to carry the albinism gene?
Yes, albinism is passed down (inherited) through families. People are born with albinism when they inherit an albinism gene from their parents. In albinism, both parents must carry an albinism gene for their child to be born with albinism.

enzymes are specific they will only fit with certain substrates explain why lactase can digest lactose but cannot digest other sugars like maltose and sucrose
Explanation:
your small your small intestines can't absorb either lactose or maltoseyou use different enzymes to digest the two sugars lactase break down lactose why an enzyme called sucrase-isomaltase breaks down maltose because enzyme are so specific with regard to function you can't break down maltose with lactose or vice versa
Lactase breaks down only lactose in food in our body can absorb it not maltose and sucrose as enzymes are specific in nature.
what are the properties of an enzyme ?Enzymes are protein which act as a catalysts and speed up the rate of biochemical reactions with out changing the structure of the final product.
Enzymes can control the speed and specificity of the chemical reaction, and the rate of biochemical reaction often influences enzymes and they can take place at a relatively low temperature; it lower the activation energy.
The enzyme activity pH specific, that is at a particular pH, each catalyst is most active for example at PH 2 for pepsin, pH 8.5 for trypsin, for example.
Both enzymes have active sites which can activate biochemical reactions. It is soluble in water, dilute glycerol, NaCl, and dilute alcohol.

Answer:
less
Explanation:
because a 30 min run can only burn 200-500 calories
In the morning, a 160-pound college student consumes a bowl of cereal with 750 calories. 30 minutes of running can only burn 200-500 calories.
What is Calories?The calorie is a type of energy unit. For historical reasons, there are two main definitions of "calorie." The large calorie, food calorie, or kilogram calorie was originally defined as the amount of heat needed to raise the temperature of one kilogram of water by one degree Celsius.Calories are the units of energy released by your body when it digests and absorbs food. The higher the calorie content of a food, the more energy it can provide to your body. When you consume more calories than you require, your body stores the excess calories as fat. Even fat-free foods can be high in calories.

Why do parrots mimic people?
Answer:
Parrots are intelligent and highly social animals with long life spans, just like people. ... So a domestically-bred parrot, such as a budgerigar, that mimics its people is doing what wild parrots naturally do: they are learning and repeating sounds made by its family and flock mates, who happen to be people.
Explanation:
Parrot expert Michael Schindlinger of Lesley University explained in Scientific American in 2007 that mimicking helps parrots separate members of their own community from outsiders. It can allow a bird to find its mate and prevent intracommunity conflicts over territory.

what are the similarities between this activity and actual mitosis
The DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.
What is mitosis?Mitosis is defined as the cell-division process in which the chromosomes multiply and are equally distributed between the two daughter cells. Prophase, Prometaphase, Metaphase, Anaphase, and Telophase are the five stages that make up mitosis. Meiosis is defined as a process by which a single cell undergoes two divisions, resulting in four cells with half the original genetic material.
Cell division occurs during meiosis as well as mitosis. The M-phase of the cell cycle is where both processes take place. The prophase, metaphase, anaphase, and telophase stages are typical for both cycles. DNA synthesis occurs during both cycles. A common goal of meiosis and mitosis is the division of the nucleus and its DNA into two daughter cells.
Thus, the DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.
